查询词典 arc

Saddle shaped AMF can produce a radial expanding force, which has more effective effect on resisting the pinch effect of self-generated azimuthal magnetic field of arc current. This effect of saddle shaped AMF can keep vacuum arc in diffuse mode under much higher current. So the limiting current interruption capacity of vacuum interrupter can be enhanced.

为了进一步提高纵向磁场对真空电弧的控制作用，本文提出在真空灭弧室的触头间引入从触头中心向边缘逐渐增强的非均匀纵向磁场，马鞍形纵向磁场会对真空电弧产生一个径向扩张力，而纵向磁场分布的合理设计可以使这一扩张力进一步抑制真空电弧自生环向磁场对电弧的箍缩作用，从而使真空电弧在更大的电流时仍能保持在扩散态，使真空灭弧室的极限电流开断能力得以提高。
